Yes, I see the pattern. I just showed you the pattern. Democrats are, as a whole, slowly but surely moving to the left.
Unless you have actual evidence that that pattern has changed in the last four years, besides 'trust me bro', I see no reason to believe it has changed.
Now, if you were to say "I wish the Democrats would move left faster", then you would have a point. Of course with your average slightly left of Democrats voter being too lazy to get off their ass and vote, or as they say "taking a principled stand against the system [by sitting quietly at home and not bothering anybody]", it makes perfect sense why Democrats would ignore the desires of those people who don't vote. I also think there's no need to listen to the political opinions of a nonvoter.
